Induction machines play a vital role in industry and there is a strong demand for their reliable and safe operation. Failure of its performance leads to shut down and loss of revenue as well as time. Bearing Fault accounts to maximum percentage among all faults pertaining to Induction machines. This paper presents approach to determine severity of cage fault in bearing with the help of dynamic model based on contact mechanics applied to case of external harmonic excitation. The paper focuses on air gap variation to predict fault frequencies and loss of stiffness in rolling element bearings.
